The liquid tank 1020 is connected, and a pump 1010 is also arranged on the liquid delivery pipeline; the secondary electrolyte tank 1040 is a membraneless electrolytic cell, and the first-level hypochlorous acid solution 1050 in the anode chamber of the first-level electrolyte tank 1020 is connected to the second level through the communication pipeline. Level electrolyte tank 1040 is connected, and the primary hypochlorous acid solution 1050 in the anode chamber of the primary electrolyte tank 1020 is electrolyzed again in the secondary electrolyzer, to obtain secondary hypochlorous acid solution 1060, secondary hypochlorous acid solution 1060 The acidity is less than the acidity of the primary hypochlorous acid solution 1050; the concentration monitoring part 1030 is arranged on the communication pipeline; The concentration of the chloric acid solution 1050 controls the working state of the pump 1010 to keep the concentration of the primary hypochlorous acid solution 1050 stable.

Specifically, the water in the water inlet pipeline and the electrolyte solution 900 in the electrolyte storage unit 400 enter the primary electrolyte tank 1020 to mix, and after mixing, an electrolytic reaction occurs in the primary electrolyte tank 1020, so that electrolysis Under the action of the cation exchange membrane, the negatively charged chlorine ions of the final liquid enter the anode chamber for oxidation reaction to form a hypochlorous acid solution, and the sodium ions enter the cathode chamber for a reduction reaction, that is, the primary hypochlorite formed after electrolysis The acid solution 1050 enters into the anode chamber; the hypochlorous acid solution inside the anode chamber enters into the second membraneless electrolytic cell for secondary electrolysis to obtain a secondary hypochlorous acid solution 1060 .

Of course, in this embodiment, the electrolyte is not limited to be NaCl or NaCl solution, and other types of electrolytes may also be used, as long as the electrolyte can realize electrolysis and generate hypochlorous acid.

At the same time, in this application, a concentration monitoring unit 1030 is set between the secondary electrolytic tank and the primary electrolyte tank 1020 to monitor the primary hypochlorous acid, and the controller monitors the primary hypochlorous acid through the concentration monitoring portion 1030. The concentration of the acid controls the working state of the pump 1010, so that the primary hypochlorous acid solution 1050 generated by the electrolytic reaction after the electrolyte solution 900 and the water inlet pipeline enters the interior of the primary electrolyte tank 1020 maintains a stable concentration to avoid occurrence of Changes in the liquid intake of the water inlet pipeline lead to the phenomenon that the concentration of the secondary hypochlorous acid solution 1060 is different from the target concentration, which improves the stability of the concentration of the secondary hypochlorous acid solution 1060 . Under the control of the controller, this solution can monitor the concentration of the primary hypochlorous acid solution 1050 in real time, so as to improve the intelligence of the hypochlorous acid disinfection water machine, and only need the user to provide the electrolyte solution 900 to obtain the secondary electrolytic solution. No need to process the secondary hypochlorous acid solution 1060 obtained by secondary electrolysis, and the operation is simple and convenient.

Further, in the interior of the primary electrolyte tank 1020, the primary electrolyte tank 1020 is divided into a cathode chamber and an anode chamber with the cation exchange membrane as the boundary. After the electrolysis reaction occurs in the primary electrolyte tank 1020, the anode chamber A primary hypochlorous acid solution 1050 is formed inside and leads to the secondary electrolyte tank 1040. The sodium hydroxide formed inside the cathode chamber is discharged through the discharge pipeline 500 and collected as waste water. A flow limiter can be set on the discharge pipeline 500 The valve 1070 is used to control the on-off of the discharge pipeline 500 and the speed of liquid discharge. By controlling the flow rate inside the discharge pipeline 500 , the mixing ratio of the electrolyte solution 900 can be controlled.

Wherein, the primary hypochlorous acid solution 1050 is a pure hypochlorous acid solution, the pH value of the pure hypochlorous acid solution is between 3-4, and the pH value of sodium hydroxide is between 9-10.

In this implementation, the hypochlorous acid solution is obtained by electrolyzing NaCl solution. The user only needs to provide NaCl or NaCl solution. It may be provided with a salt bottle, which is used to place NaCl or NaCl solution. It communicates with the primary electrolyte tank 1020 to pass NaCl or NaCl solution to the inside of the primary electrolyte tank 1020 .

Further, the user can put NaCl crystals and NaCl powder into the inside of the salt bottle, so that the NaCl crystals and NaCl powder enter the primary electrolyte tank 1020 and then electrolytic reaction occurs inside the primary electrolyte tank 1020; the user can also The NaCl solution is poured into the salt bottle, so that the NaCl solution is input into the primary electrolyte tank 1020 and an electrolysis reaction occurs inside the primary electrolyte tank 1020 .

Of course, the specific placement form can be adaptively adjusted according to user needs.

Inside the primary electrolyte tank 1020, water and the electrolyte solution 900 are mainly electrolyzed, and inside the secondary electrolyte tank 1040, the primary hypochlorous acid solution 1050 is mainly electrolyzed for the second time to generate secondary hypochlorous acid Solution 1060, the acidity of the secondary hypochlorous acid solution 1060 is reduced, and has a good effect of oxidation and sterilization.

It should be noted that the controller can be electrically connected to the voltage stabilizing part 700, the flow limiting valve 1070, the primary electrolyte tank 1020 and the secondary electrolyte tank 1040 at the same time, according to the required concentration of the secondary hypochlorous acid solution 1060 Control the current of the primary electrolyte tank 1020 , the current of the secondary electrolyte tank 1040 , the power of the pump 1010 , the working state of the voltage stabilizing part 700 , the working state of the current limiting valve 1070 and the power of the pump 1010 . Under the control of the controller, the current of the first-stage electrolyte tank 1020, the current of the second-stage electrolyte tank 1040, the power of the pump 1010, the working state of the voltage stabilizing part 700, the working state of the current limiting valve 1070 and the power coordination of the pump 1010 action to ensure the concentration of the secondary hypochlorous acid solution 1060.

In this application, the pump 1010 is a peristaltic pump, and the power and pump speed of the peristaltic pump are set by an electronic control program.

As shown in Figure 1, the concentration monitoring part 1030 includes a flow sensor, the flow sensor is used to monitor the flow of the primary hypochlorous acid solution 1050 in the communication pipeline, and the controller adjusts the power of the pump 1010 according to the flow change situation monitored by the flow sensor, To keep the concentration of the primary hypochlorous acid solution 1050 stable.

Further, the flow sensor monitors the flow rate of the primary hypochlorous acid solution 1050. When the flow rate of the primary hypochlorous acid solution 1050 increases, it means that the liquid inside the water inlet pipeline flows into the primary electrolyte tank 1020. more, causing the concentration of the primary hypochlorous acid solution 1050 formed inside the primary electrolyte tank 1020 to decrease, at this time the controller controls the power of the pump 1010 to increase the flow rate of the electrolyte solution 900, so that the electrolyte solution 900 and the liquid inlet pipe flow balance, so that the primary hypochlorous acid solution 1050 generated in the primary electrolyte tank 1020 is maintained at a stable concentration and flows to the secondary electrolyte tank 1040 .

Of course, it is also possible to set a concentration monitoring unit 1030 between the primary electrolyte tank 1020 and the secondary electrolyte tank 1040 to monitor the solubility of the primary hypochlorous acid solution 1050, and send an electrical signal to the pump 1010 to adjust The flow rate of the electrolyte solution 900 is to keep the concentration of the primary hypochlorous acid solution 1050 stable.

In this embodiment, the flow sensor has a preset flow rate Q1, a preset pump speed V1 and a preset minimum flow rate Q2. Among them, when the actual flow q is less than the preset minimum flow Q2, the hypochlorous acid disinfection water machine stops working and alarms; when the actual flow q is greater than the preset minimum flow Q2 and less than the preset flow Q1, the hypochlorous acid disinfection water machine is normal Work, the actual pump speed V2=q*V1/Q1; when the actual flow q is greater than the preset flow Q1, the hypochlorous acid disinfection water machine works normally, the actual pump speed V2=q*V1/Q1; when the actual flow q is equal to the preset When the flow rate Q1 is set, the hypochlorous acid disinfection water machine works normally, and the actual pump speed V2=V1.

Further, the flow sensor detects the actual flow q of the primary hypochlorous acid solution 1050 generated in the primary electrolyte tank 1020 flowing to the secondary electrolyte tank 1040. When the actual flow q is less than the preset minimum flow Q2, the primary The inside of the electrolyte tank 1020 lacks liquid, and the hypochlorous acid disinfection water machine stops working and gives an alarm.

Furthermore, it can be seen from the above that the actual flow q is positively correlated with the actual pump speed V2. When the hypochlorous acid disinfection water machine is working normally, the actual flow q is too large or too small, and the actual pump speed V2 can be adjusted to adjust the actual flow rate. The size of the flow q is such that the actual flow q is equal to the preset flow Q1, so as to prepare the primary hypochlorous acid solution 1050 and the secondary hypochlorous acid solution 1060 of the target concentration.

It should be noted that the secondary hypochlorous acid solution 1060 of different concentrations can be obtained according to the actual needs of the user, specifically the concentration value of the secondary hypochlorous acid of the required concentration is set on the controller, for example, the concentration can be 98%, 95%, 70%, etc.

Wherein, according to the different structural parts controlled by the controller, three different implementation manners are provided in this embodiment, which are as follows.

In an unillustrated embodiment, the controller is connected to the primary electrolyte tank 1020, and controls the current of the primary electrolyte tank 1020 according to the required concentration of the secondary hypochlorous acid solution 1060, so as to The concentration of chlorine ions is generated in the hypochlorous acid solution 1050 so as to generate the concentration of the secondary hypochlorous acid solution 1060 with a predetermined concentration.

Specifically, by controlling the internal current of the primary electrolyte tank 1020, to mediate the electrolytic reaction inside the primary electrolyte tank 1020, and by controlling the amount of chloride ions generated by the electrolytic reaction, to mediate the generation of the primary hypochlorous acid solution 1050 concentration.

In another specific embodiment not shown in the figure, the controller is connected with the secondary electrolyte tank 1040, and controls the current of the secondary electrolyte tank 1040 according to the concentration of the required secondary hypochlorous acid solution 1060, so as to control the secondary electrolyte tank 1040 The concentration of chlorine ions generated in the primary hypochlorous acid solution 1060 is used to generate the concentration of the secondary hypochlorous acid solution 1060 with a preset concentration.

In another specific embodiment not shown in the figure, the controller is electrically connected to the pump 1010 and controls the power of the pump 1010 to adjust the power of the pump 1010. Different powers can adjust the flow rate of the electrolyte solution 900, thereby adjusting the chlorine The concentration of ions enables the control of the concentration of the secondary hypochlorous acid solution 1060 . Of course, the controller can also control the water inlet pipeline to adjust the concentration of chloride ions by adjusting the flow of the water inlet pipeline, so as to realize the concentration of the secondary hypochlorous acid solution 1060 with a preset concentration.

Specifically, by controlling the power of the pump 1010, the pump 1010 can output different rotational speeds, and the flow rate of the electrolyte solution 900 can be adjusted through different rotational speeds to ensure that the primary hypochlorous acid solution in the primary electrolyte tank 1020 Concentration of 1050.

Size, for example, the flow rate of the liquid inside the water inlet pipeline is increased by pressurization, and then the solubility of the electrolyte inside the primary electrolyte tank 1020 is reduced to generate chloride ions with a lower concentration after an electrolysis reaction, resulting in The concentration of the secondary hypochlorous acid solution 1060 decreases accordingly. To prevent this, the internal liquid of the water inlet pipeline can be reduced through the pressure stabilizing part 700, thereby increasing the concentration of the secondary hypochlorous acid solution 1060. The principle is the same, and will not be repeated here. .

Among them, the pressure valve can realize the protective effect on the water inlet pipeline and avoid the phenomenon of water leakage, so that when the pressure of the liquid inside the water inlet pipeline is too high, the pressure inside the water inlet pipeline can be reduced by adjusting the pressure valve. Control within a safe range, such as between 0.2-0.3MPa.

Further, a solenoid valve 800 is set between the voltage stabilizing part 700 and the primary electrolyte tank 1020, so as to control the on-off of the water inlet pipeline by controlling the solenoid valve 800, so as to realize that only once in the primary electrolyte tank when it is necessary to During the electrolysis reaction, the controller sends an electrical signal to the solenoid valve 800 , and the solenoid valve 800 is in an open state, so that the liquid inside the water inlet pipeline enters the inside of the primary electrolyte tank 1020 . Of course, the electromagnetic valve 800 can also be controlled to adjust the flow rate of the liquid inside the water inlet pipeline, so as to control the concentrations of the primary hypochlorous acid solution 1050 and the secondary hypochlorous acid solution 1060 .

As shown in FIG. 1 , a filter structure 600 is also provided on the water inlet pipeline, and the filter structure 600 is located upstream of the pressure stabilizing part 700 .

Specifically, the liquid inlet of the water inlet pipeline is connected with the tap water switch, and a filter structure 600 is set on the water inlet pipeline to filter the tap water, so as to prevent the impurities inside the tap water from entering the inside of the primary electrolyte tank 1020 and affecting the primary electrolysis. reaction, resulting in affecting the production of the primary hypochlorous acid solution 1050.

Of course, the liquid inlet of the water inlet pipeline may also be in communication with other structures or devices that provide liquid, and the filtering structure 600 shall be subject to the ability to filter the liquid inside the water inlet pipeline.

Further, the filter structure 600 can remove impurities such as calcium and magnesium ions in the water, reduce the adhesion of calcium and magnesium ions and other substances on the electrolytic sheet to affect the effect of electrolysis, and at the same time realize the protective effect on the electrolytic sheet and improve the electrolytic sheet. service life.
